CAR CONSTRUCTION.

Application filed May a0, 1926. Serial No. 110,392.

My invention relates to improvements in car construction and moreespecially to an improved car side construction for hopper cars and thelike.

It is anobject of my invention to improve the construction of a carhaving hoppers below the side walls, whereby the lower margins of thesides will be inwardly offset, and suitably rigidified and braced toform supporting means for said hoppers.

It is also an object of my invention to provide suitable constructionwhereby a car having inwardly offset sides extending only between bodybolsters, may be suitably connected in an effective manner with the endsills of the car, and continuity of reinforcementaflorded between theend sills of the car.

It is also a further object of the invention to adapt an offset sideconstruction to perform the function of a load carrying chord and tobrace the same against bulging and buckling and protect the partsentering into the construction thereof against corrosion.'

Other objects and advantages of the invention will be more clearlypointed out herein- 7 Referring to the drawings, Fig. 1 is a sideelevational viewof a portion of a hopper car embodying my improvements,a portion of the side wall at the left of the figure being broken awayto better illustrate the cross beam construction. Fig. 2 is a brokenhorizontal sectional view, illustrating the sidewall and adjoiningconstruction, said section being taken on a linecorresponding substan-Fig. 3 is an enlarged fractional sectional plan view of a ortion of thecar taken ad'acent the outer end of the bolster, and on a inecorresponding substantially-to line 3-3 of Fig. 1, said viewillustrating the connection between the main side wall and adjacentbrace which extends from the bolster to the end sill of the car. Fig. 4is an enlarged fractional transverse sectional view taken throu h thelower portion of the car side wall and opper on a line correspondingsubstantially to line 4-4 of Fig. 1. Fig. 5Iis an enlarged fractionaltransverse sectional view, somewhat similar to Fig. 4, except that thesection includes one of the side stakes, said view being taken on a linecorresponding substantially to line 55'of Fig. 1. Fig. 6 is an enlargedtransverse sectional view showing approximately one of the cross-membersof the car, F the end Slll of the car, G one of the side bracesextending from bolster to end sill, H one of the connecting gussetsbetween the main side wall and adjacent side brace, and J one of thedischarge hoppers disposed below. the

' side wall and 'center sill of the car. Only one end portion of the caris shown, it being understood that both ends of the car are of similarconstruction, and the number of cross-members and hoppers intermediatethe body bolsters will vary depending on the len th and construction ofthe car.

he side walls A are spaced outwardly for the major portion of the lengthof the car to substantially the maximum allowable road clearances, inorder to gain increased carrying capacity between the side walls of thecar. The side walls A are each formed of a plate 10 having a verticallyextending main portion and an inwardly and downwardly bent flange 11 atthe lower margin thereof, for a purpose aswill be hereinafter fullypointed out. The upper margin of the car side is provided adjacent thetop with a suitable rigidifying member 12, which is secured to the topmargin of the plate 10, the platev 10 at the top of the car side beingbent inwardly as indicated at 13 to dispose said rigidifying member 12within the'car side clearances. Adjacent the end of thg car a portion ofthe side wall of he car as indicated at 14 is disposed inwardly of themain plane of the said car sidewall thereby presenting narrowed bodyportions at the ends of the car. The transition from the planes of therespective walls is effected byan angularly related wall section asindicated at 15. In the re cesses thus presentedby the narrowed end bodyportions there are disposed a series of ladder treads 16.

Secured tothe inwardly and downwardly inclined flange '11 of the carside plate 10 is a rigidifying member 17 which is pref:

erably in 'the form of a flanged member with one of its flanges 18overlying the said flange 11 and extendingin the same general direction,and having its adjacent flange 19 outstanding from the said first namedflange, the member 18 extending longitudinally of the car between thebody bolsters D, and being directly secured thereto and to therespective cross members E by means of rivets extending through theflange 18 and the outer ends of the respective cross members.

The cross members E of the car include transverse vertical wall members20 which extend between the respective side walls and center sills ofthe car as shown in Fig. 6, only one half of the car being shown in saidfigure, but it will be understood that the construction is similar onboth sides of the center sill. 1

Connection between the side wall 10 of the car and the plate member 20is effected by an integral flange 22 formed on one side of the plate,and aseparate angle shaped member 23 on the opposite side of said plate,the said member 23 being also bent adjacent its lower portion, andextended over the inwardlyv directed lower margin of the car side andsecured ,thereto by a series of rivets. Connection between thetransverse plate 20 and center sill C is also effected by an integralflange 24 on one side of the plate and a separate angle connection 25 onthe opposite side thereof.

The transverse plates 20 on the opposite sides-of the center sill C aretied across The plane of the center sill by an angle shaped tie member26, and by inclined shedding plates 27-27,' said last named platestogether forming a transverse load shedding ridge sloping longitudinallyof the car. The lower margin of each plate 20 of the cross member E isrigidified by an angle shaped member 28, said member at its outer endbeing bent upwardly at 29, to overlap the inwardly directed portion ofthe car side. The said angle shaped member 28 is disposed on the side ofplate 20 opposite to the vertical angle member 23, and said membersoverlap and are united together and to the plate 20 by means of rivets129, thereby forming aT construction of great strength.

The crossbeam sections 2020 are also tied h a lower plate 30 extendingacross the plane of the center sill. The inwardly directed portion ofthe car side is also tied to the crossbeam 20 by a gusset plate 31-,which is secured to the outstanding marginal flange 19 of the rigidifyinmember 17, and to the horizontal flange o the angle member 28. Therespective flanges 18 and 19 of the angular member 17 are braced atsuitable intervals by bracket members 32 which are riveted to therespective, flanges thereof.

The heavy angular shaped members 17 are preferably adapted to extendonly between the body bolsters D, being connected to the outer endthereof, as shown in Figs. 3 and 7. Each bolster D includes a verticalweb plate 33 having lower marginal angle shaped reinforcements 34 and 35along the bottom edge thereof, said angles being bent upwardly asindicated at 134 and 135, to conform to the shape of the car side, andadjacent the Quter end of the car side there are vertically extendinginner and outer angles as indicated at 36 and 37 respectively, said lastnamed members being connected to the vertically extending portion of thecar side wall. The angles 36 and 37 are also extended downwardly, andbent as indicated at 136 and 137 respectively to conform to the shape ofthe inwardly directed portion of the car side. The downwardly bentportions 136 and 137 of the members 36 and 37 overlap the upwardly bentportions 134 and 135 of the members 34 and 35, and the overlappingportions are rigidly united to each other and to the web plate 33 by arivet'38. The overlapping portions of the angle members thus providecontinuous lateral flanges along the edges of the'web plate 33 of thebolster.

Connection between the angle member 17, and the bolster, is effected byriveting flange 18 to the lateral flanges of the bolster where they areoverlapped, and also by riveting the outstanding flange 19, of the anglemember 17 to the bolster cover plate 39, which is formed to project onopposite sides of the lateral flanges on the bolster, and extendedoutwardly beneath the said outstanding flange 19. A jacking plate 40 isdisposed beneath the end of the bolster and outstanding flange 19 of theangle member 17.

The angular member 17 is further secured to the car side adjacent thebolster through the medium of gusset member H which forms aconnectionbetween the end brace G, and the vertical car wall section.The gusset member H is formed with portions extending respectively aboveand below the brace, the upper portion being'disposed between thevertical car side wall, and the outer vertical bolster connecting angle37, while the lower extension isv bent inwardly to underlie fiange-18 ofthe vertical member 17 and is secured thereto by rivets 41, saidunderlying portion of the gussetmember being in the same plane as theinwardly bent flange 11 of the car side wall, a section of the saidgusset being out out as indicated at 139 and 140 to clear the flange 11.

Each brace G is extended to the end sill of theicar, and suitablyconnected therewith at thecorner post 42 in the'usual manner.

The length of the end sill coincides suband each end brace G isdeflected inwardly as indicated at 43, to permit of the attachment ofthe respective ends to portions of the car in different vertical planes.

Extending transversely of the car above the body bolster is the slopingfloor 44 which lower slopes longitudinally of the car towards the centerthereof to the lowerhopper J, said floor terminating at a dischargeopening 45 which is adapted to be closed by a transversely extendingdoor 46. A longitudinally extending side floor sheet 47 is secured tothe car side and sloping floor sheet 44, thereby forming with thedumping door 46 the hopper section J. The side 'floor sheet 47, as bestillustrated in Fig. 4 is bent to present a vertical section 48 forattachment to the vertical side wall sheet, and is then bent to slopedownwardly and inwardly asat 49 to present a shedding plane overlyingthe angular member 17, and thereafter it is bent downwardly at a steepangle and extended below the side of the car to form the main side wallof the hopper section J. The said floor sheet 47 extends longitudinallyof the car from the cross member shedding plate 27 to the sloping floor44, thereby presenting an efiicient sealing member to close the jointsbetween the main side wall sheet and the lower angular member to preventseepage of water and moisture between the joints, and it thus retardscorrosion of the parts.

The sloping section 49 of the side hopper sheet is secured directly tothe flange 18 of the member 17, as indicated at 50, and also by rivets51 extendin throu h the section 49, the member 17, an the underlyingflange 11 of the side wall. The side floor sheet 47 is flanged asindicated at 52 and 53, which flanges respectively are secured to thesloping floor sheets 27 and 44.

At certain intervals in the length of the car side wall vertical bracesas indicated at 54 and 55 are disposed on the inner side of the carwall, said members being extended downwardly over the sloping portion ofthe side wall and riveted thereto as at 56, said construction being bestindicated in Fig. 5. i

It will thus be seen that my invention provides a strong constructionwhich forms an adequate support for the lower hopper sections androvides for continuity of reinforcement in the car side wall between theends of the car, whereby bufling shocks may be efl'ectively transmittedwithout buckling or bulging the side walls. The disposition of theoutstanding rigidifying flange in the lower chord of the car sideimmediately at the junction of the sloping car side and the hopper J,and the tying of the said flange to the cross members by gusset platesensures a very rigid construction against bulging of the car'sides. Theformation of the car side and disposition of the lower chord member toconform to the load containing capacity of the car provides for maximumcarrying capacity and the novel arrangement of the car side and sidehopper floor sheet effectively protects the said lower the combinationwith a side wall.
